18143 (2000 OK48) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2000 OK48 as potentially hazardous because its orbit does not bring it close to Earth.
2000 OK48 orbits the sun every 1,710 days (4.68 years), coming as close as 2.26 AU and reaching as far as 3.34 AU from the sun. Based on its brightness and the way it reflects light, 2000 OK48 is probably between 4.271 to 9.551 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
2000 OK48's orbit is 1.27 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2000 OK48's orbit is determined by observations dating back to Oct. 4, 1986. It was last officially observed on July 1, 2023. The IAU Minor Planet Center records 2,070 observations used to determine its orbit.
